tests: virstoragetest: Remove "expBackingStore" field

Now that we changed ordering of the stored metadata so that the backing
store is described by the child element the test should reflect this
change too.

Remove the expected backing store field as it's actually described by
the next element in the backing chain, so there's no need for
duplication.
